Ryzen voltage very low under load

Me think you missed the part where I actually said "whether you trust the VRM sensors or the on-die dLDO is up to you". Use common sense: two voltages reported by different sensors in different parts of the system are reporting the same value within 5mV. Do you really think a correct measure...

Ryzen voltage very low under load

forgot to add the reason why I'm certain you're not running at any voltage lower than 1,264V. Check SiliconLottery's OC stats: unfortunately, they didn't test AVX2 (Prime95 v29 and up) when Summit Ridge was mainstream but luckily we have those stats for Threadripper's iteration of Summit Ridge...

Ryzen voltage very low under load

that's certainly not the voltage you're running at. I've highlighted the areas of your previous hwinfo64 screenshot to give you an idea of what you're looking at. Whether you trust the on-die sensors or the MoBo VRM sensors is up to you, although from 1,269V to 1,264V there's little to worry...

Ryzen voltage very low under load

Chances are CPU-Z was previously reading SVID=Vcore, and something in the new BIOS is telling CPUz to stop it and read the proper Vcore, which has now confused hwinfo64's SVID who is reading actual Vcore. As far as I'm concerned, whatever you read in hwinfo64's MoBo sensors as "Vcore" is the...

Question i9 9900K OC help!

for some unfathomable reason, it looks like MoBo makers did not get the memo about the improved memory controller on 14nm+(+) Coffee Lake so they keep shoving the same voltages as Skylake. From my own testing and lurking BIOS forums, seems that most MoBos default to 1.30VccIO and 1.35VccSA for...

Intel is dropping hyperthreading from i7 chips!

https://ark.intel.com/es/products/135935/Intel-Core-i5-8259U-Processor-6M-Cache-up-to-3_80-GHz yeah... I thought that before too. Then they released 4c/8t 8th gen mobile i5s with 6MB cache. It's all artificial market segmentation, just like with the PCIe lanes on X299.

Coffeelake thread, benchmarks, reviews, input, everything.

hmm, that PL2 is oddly close to the power consumption that a "good sample" of 8700K draws during a similar torture test with MCE settings (47x cores, 44x cache) MCE draws almost exactly 120.6W/1.210V=100Amps average during torture testing, I've seen this aswell on a "bad sample" of 8700K and...

What's Intel's roadmap going forward?

They're following the same naming convention: every time they make a new iteration of the Core architecture (meaning: increase in IPC clock-for-clock with normalised RAM speed and timings), they switch to a new kind of landmark. Initially: Bridges: Sandy Bridge (tock, architecture) ; Ivy Bridge...

8700k overclock issues?

according to their QVL yes, up to 3200Mhz https://siliconlottery.com/pages/intel-coffee-lake. It shouldn't be a problem with Coffee Lake unless you're aiming over 4200Mhz though, I've tested two 8700k and Intel's claims of "better memory overclocking" seem accurate. Both did 4000Mhz with tight...

8700k overclock issues?

Battlefield 1 runs on the same engine as Battlefront 2 (Frostbite 3 iirc), and it's known for crashing overclocks that are stable elsewhere. I think it uses some sort of AVX instructions but it somehow doesn't pull all the voltage the CPU needs to do so. I've experienced it first-hand with a...

Ryzen: Strictly technical

Oh, that certainly solves me a somewhat related enigma. When I googled the IC part number of my two kits of DDR4, oddly enough, the maximum sustained operating voltage according to the specsheets is 1,5V for both Hynix MFR and Samsung B-die ICs. It was a bit mind-boggling, considering the...

Should I RMA i7 6700K? (Read Description) Thanks

If you absolutely, positively, 100% know for sure that it has been running for long periods of time near thermal throttling (which is 95ºC, not 100ºC); chances are yes, the CPU could be degraded and thus producing stuttering... But sanity checks first: have you updated the BIOS to the latest...

AMD Ryzen 5 2400G and Ryzen 3 2200G APUs performance unveiled

nice clocks indeed, but notice that they halved the L3 cache of the CCX (4MB instead of 8MB in regular Ryzen5 1400). Is that enough to drastically reduce power per clock cycle? I'm curious to see whether it impacts single threaded performance or if it's just going to have an impact on SMT gains.

I'm not even surprised, to be honest. It's clearly not a bug but a feature for Intel Agencies. Sorry for the mediocre pun :p

I can't even grasp what they're doing with this 8th gen. A month after Z370 launch, and Z390 already spotted in the wild. no 8-core like the rumors said, tho

absolutely, specially if the CPU is kinda old. I own a 6600k since november 2015 and the TIM was severely degraded (thanks Intel! /s), to the point that I've improved 30ºC in package temps after delid + liquid metal. This is how the TIM looks and performs in a 2-year old 6600k: and this is...

this compilation from Broda (@tweakpc.de) shows ASUS only used 1 controller and 2 different mosfets in their latest Intel launch (Z270). The "Maximus" boards have top notch Texas Instruments mosfets while the rest of the stock has mosfets manufactured by ON Semiconductors. To the best of my...

so I just saw this reposted in hardforum, original source Baidu. Can't give it much credibility, what do you guys think? DDR4 speeds trigger my fake-meter up to the redzone, and so does LGA1161 and LGA2076. edit: original post http://tieba.baidu.com/p/5353174380

Ryzen: if can't run full (3200MHz) speed, is DDR4-3000 CL15 faster than DDR4-3200CL16 b/c of the CL?

TLDR: think in nanoseconds for real-world latency comparation. 3000Mhz = 3000*1000² clock cicles per second at double data rate (DDR4), so clock cicle=1/(1500*1000²) seconds= 0.6666 nanoseconds. Then simply multiply by CAS latency to get the actual "total completion time", which is the total...

2.5 VCore?! This can't be right.

There's some MoBos reporting wrong voltage readings for CPU-Z, like the Taichi. Video linked to the timestamp where Tiny Tom Logan mentions it: https://youtu.be/U5IpXvOFtPU?t=852 his CPU-Z screenshot was showing 2'848V while Vcore was set in BIOS to 1'42V. HWiNFO64 reported accurate readings...
